I have various tokens that run on bitcoin that are trapped in my multibit wallet. One example is OMNI Mastercoin but there are a couple of others. The problem is that the amounts, stored as tagged BTC of much lower value, are too small to cover the fixed multibit fee of sending them out of the wallet. They're only small values, but in principle I don't like the idea of having trapped coins. What is my best option to release them? e.g. Can I set send transaction fee to 0? Can I import the address and tokens into another wallet and how? Thanks for any solution.
